🏆 Who will win Rays vs. Orioles?
The Orioles got swept by the Yankees, draining their momentum. However, Baltimore went 3-1 SU against the Rays in their last series before returning home. Rogers has a significant pitching edge against Peralta, so expect a strong outing from the Orioles, leading to a 5-1 win at Camden Yards tonight.
Score prediction: Orioles 5, Rays 1
💰 Rays vs. Orioles prediction & best bet
First 3 Innings: Under 2.5 total runs (-125)
The last time we saw Freddy Peralta and Trevor Rogers make their respective starts was Baltimore's 10-2 road win on August 16th. Despite the high-scoring affair, Peralta and Rogers each held the opposing lineup without a run through the first 3 innings.
Rogers has held four of his last five lineups faced to 2 or fewer earned runs. He only has three walks in his last five starts as well, so the Rays won't be getting much traffic on the bases the first time through their lineup.
Peralta limited the Orioles lineup to one hit in his last outing. Let's bet on the First 3 Innings: Under 2.5 Total Runs at -125 odds on DraftKings.
📡 SBR Edge: Camden Park
The Orioles' last six home games played at Oriole Park at Camden Yards have finished under the total runs line.
🔥 Best Rays vs. Orioles player prop bet
Jonny DeLuca Under 1.5 hits + runs + RBIs (-130)
Jonny DeLuca has been on the schnide in the Rays' lineup lately. Tampa Bay's CF has gone Under 1.5 hits + runs + RBIs in three of his last five starts. DeLuca draws a tough matchup against Rogers, who has held three consecutive lineups to 2 earned runs in each start.
Rogers' ability to avoid putting runners on base with limited walks is what really makes me like fading DeLuca. DeLuca has recorded two hits, two RBIs, and no runs across his last five starts for the Rays.
Let's go to BetMGM and place a 2 unit wager on Jonny DeLuca to finish Under 1.5 hits + runs + RBIs at -130 odds.
💣 Rays vs. Orioles home run prediction
Pete Alonso to hit a home run (+350)
The Orioles have already had a strong return on investment with their Pete Alonso trade this past offseason. Baltimore's 1B is the definition of a power hitter, ranked 98th in xSLG (.544), 99th in avg exit velo (94.2), and 98th in hard-hit percentage (56.3) in 2026.
Alonso enters tonight's game with two home runs logged across his previous four starts. He has a barrel percentage of 14.0, which also puts him in the 91st percentile. Peralta had a strong outing last time out against Alonso but he's still ranked in the ninth percentile for pitching run value (-12) this season.
Let's back one of the favorites on the board tonight in the home run player prop market. Bet Pete Alonso's home run prop at +350 odds on bet365.

💡 How I'm betting Rays vs. Orioles: MLB strategy
Follow all of our MLB analysis and expert predictions for baseball season.
I'm feeling confident in tonight's A.L. East tilt between the Rays and Orioles. It's why I'm staking 2.5 units on a First 3 Under 2.5 prop as my best bet in this game. Then, dropping another 2.6 units on Jonny DeLuca to finish with Under 1.5 Hits+Runs+RBIs. Each of these bets would win 2 units of profit.
A smaller 0.30-unit play on Pete Alonso's home run prop yields just over 1 unit (1.05) of profit. Then, an SGP with legs containing an NRFI and Extra Innings: No comes out to -103 odds on FanDuel, which warrants a 1.03-unit wager to win 1 more unit of profit.
